The config bundle handed to run_agent_loop / run_agent_loop_continue. Mirrors TS AgentLoopConfig. Hook fields are Option except convert_to_llm (required). The provider-options subset (api_key, timeout, cache_retention, session_id, max_retries, max_retry_delay, signal) is kept as plain fields the loop stuffs into a SimpleStreamOptions per turn.

Fields

model: Model

convert_to_llm: ConvertToLlm

Required: AgentMessage[] → Message[]. Never None at call time; the AgentBuilder installs default_convert_to_llm (drop custom roles) when the caller doesn’t supply one.

transform_context: Option<TransformContext>

get_api_key: Option<GetApiKey>

should_stop_after_turn: Option<ShouldStopAfterTurn>

prepare_next_turn: Option<PrepareNextTurn>

after_tool_results: Option<AfterToolResults>

get_steering_messages: Option<GetSteeringMessages>

get_follow_up_messages: Option<GetFollowUpMessages>

before_tool_call: Option<BeforeToolCall>

after_tool_call: Option<AfterToolCall>

tool_execution: ToolExecutionMode

Per-batch execution mode. Default Parallel.

thinking_level: ThinkingLevel

api_key: Option<String>

timeout: Option<Duration>

max_retries: Option<u32>

max_retry_delay: Option<Duration>

cache_retention: CacheRetention

session_id: Option<String>

signal: CancellationToken

Cancellation token for the whole run. The loop clones a child per tool.

Implementations

impl AgentLoopConfig

Build a SimpleStreamOptions from this config’s provider-options subset, overriding signal with the run’s token. Mirrors the TS spread { ...config, apiKey: resolvedApiKey, signal } passed to streamFunction.

pub fn to_stream_options(&self, api_key: Option<String>) -> SimpleStreamOptions

Trait Implementations

impl Clone for AgentLoopConfig

fn clone(&self) -> AgentLoopConfig

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for AgentLoopConfig

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.
